Duemillinovae error

Hi, I just received my Duemillinovae board in the mail. I'm using a Intel based MacBook Pro and installed the proper Intel drivers. The board is connected via USB and receiving power properly.

I tried uploading a simple sketch that would make the LED light blink and received this error message. Could someone tell me what I'm doing wrong?

avrdude: stk500_getsync(): not in sync: resp=0xcd avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x20

the same problem that everyone has at the moment, I guess. here is the solution: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1237844360/1#1
